The below 21 are the major tribes with real land to their name.
There are smaller tribes within the larger tribes. Most are allied with the larger tribe that owns their land, but some are their own force, but don’t command enough power to be properly recognized by the rest of the tribes. Usually these minor tribes are just families who had some high status before, and are attempting to own the land they owned before the fall. Some are smaller tribes that were basically brushed aside during the earlier battles, and became protectorates.
